Data needs depend on how much time you spend away from Wi-Fi, the video quality you stream and whether you share a mobile hotspot with other devices. These are broad budgeting guidelines, not precise usage predictions.
Light use: roughly 5–10GB
Messaging, maps, email and some browsing, mostly on Wi-Fi, may fit within a smaller plan.
Mixed use: roughly 20–50GB
Frequent social feeds, short videos, music and web use away from Wi-Fi can warrant a moderate allowance.
Heavy use: 100GB or unlimited
High-definition streaming, daily tethering or regular large downloads may justify larger allowances. Unlimited plans can have fair-use or speed policies, so check terms.
Practical steps
- Open your phone’s mobile data settings and review recent usage.
- Compare at least two representative months if possible.
- Allow some headroom for travel, changes in work or new apps.
- Check whether your new provider offers an app to track data.
